Functional, Material, and Characteristic Analysis of 201V12503-0062 Diesel Fuel Filter Element
Function
1. Contaminant Filtration
The primary function of the 201V12503-0062 diesel fuel filter element is to trap metallic particles, gums, and organic impurities present in the fuel. This prevents these contaminants from entering precision components such as fuel injectors and high-pressure fuel pumps, thereby avoiding blockages or wear-related engine failures.
2. Water Separation
The filter element features oil-water separation capabilities. It physically precipitates or adsorbs free water in the fuel using specialized materials, reducing the water content in diesel. This prevents water-induced corrosion of fuel system components (e.g., injectors, fuel pumps) and ensures optimal combustion efficiency.
3. Engine Lifespan Extension
By deeply filtering contaminants and water, the filter element minimizes issues such as injector clogging and high-pressure fuel pump wear. This reduces the risk of engine performance degradation (e.g., power loss, black smoke emissions) caused by fuel contamination, ultimately extending the engine's overall lifespan.
Materials
1. Composite Filter Paper
The main body of the filter element is constructed from multi-layer composite filter paper. Its pleated design increases the filtration area (e.g., 1.0㎡), enhancing contaminant interception efficiency. The composite filter paper balances strength and filtration precision, effectively trapping particles ≥5 microns in diameter.
2. Polymer Materials or Felt (for Certain Models)
Some filter elements may incorporate polymer materials or felt as auxiliary filtration layers to improve adsorption of gums, water, and other specialized contaminants.
3. Sealing Component Materials
Rubber or silicone seals may be used at the end caps or interfaces of the filter element to ensure tight sealing with the fuel system and prevent leaks.
Characteristics
1. High-Precision Filtration
The filter element achieves a filtration precision of 30μm (microns), capable of intercepting most fine particles. This meets national and Euro emission standards and is suitable for precision fuel systems such as common rail injectors.
2. Large Filtration Area
The pleated design of the filter element provides a filtration area of 1.0㎡, increasing contaminant holding capacity and extending the filter's service life, thereby reducing replacement frequency.
3. Common Rail System Compatibility
Specifically designed for high-pressure common rail engines, the filter element withstands the impact of high-pressure fuel, ensuring stable filtration performance under high-pressure conditions.
4. O-Ring Integration or Unified Structure
Some filter element models may incorporate O-rings or adopt an integrated design to simplify installation and reduce the risk of leaks caused by improper sealing.
5. Specialized for Construction Equipment
The filter element is suitable for engineering vehicles such as CNHTC's Howon, HOWO T7H/T5G, and meets the fuel filtration requirements of heavy-load, high-dust operating conditions.
